You earn higher interest rates on balances over $25,000. The interest rate under $25,000 is still competitive, just a slightly lower rate.

Radius Bank offers a variety of business accounts. Four different checking accounts are available. The accounts vary in benefits. This allows you to find the best fit for your business. A money market account and CDs are available for businesses also.

To earn the highest interest rates for the Radius savings account, you must have $25,000 in the account. Any amount over $10 earns interest. Those rates are low; similar to typical bank rates. Having $2,500 in the account will earn much higher rates. Rates for balances over $2,500 are good but still less than the interest you earn if you have over $25,000. To earn interest on your Radius checking account balance, you must have $2,500 in the account. Any amount less does not earn interest.
